Georg von Békésy (Hungarian: Békésy György, pronounced [ˈbeːkeːʃi ˈɟørɟ]; 3 June 1899 – 13 June 1972) was a Hungarian-American biophysicist.[1]
By using strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound. Because of the structure of the cochlea and the basilar membrane, different frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea.[2] High frequencies cause more vibration at the base of the cochlea while low frequencies create more vibration at the apex.[3]
He concluded that his observations showed how different sound wave frequencies are locally dispersed before exciting different
In 1961, he was awarded the Nobel Prize in Physiology or Medicine for his research on the function of the cochlea in the mammalian hearing organ.[4]
Biography
Békésy was born on 3 June 1899 in Budapest, Hungary, as the first of three children (György 1899, Lola 1901 and Miklós 1903) to Sándor Békésy (1860–1923), an economic diplomat, and to his mother Paula Mazaly.
The Békésy family was originally
Békésy went to school in Budapest, Munich, and Zürich. He studied chemistry in Bern and received his PhD in physics on the subject: "Fast way of determining molecular weight" from the University of Budapest in 1926.
He then spent one year working in an engineering firm. He published his first paper on the pattern of vibrations of the inner ear in 1928. He was offered a position at
Before and during World War II, Békésy worked for the Hungarian Post Office (1923 to 1946), where he did research on telecommunications signal quality. This research led him to become interested in the workings of the ear. In 1946, he left Hungary to follow this line of research at the Karolinska Institute in Sweden.
In 1947, he moved to the

Research
Békésy contributed most notably to our understanding of the mechanism by which sound frequencies are registered in the inner ear. He developed a method for dissecting the inner ear of human cadavers while leaving the cochlea partly intact. By using strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound. Because of the structure of the cochlea and the basilar membrane, different frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea.[2] High frequencies cause more vibration at the base of the cochlea while low frequencies create more vibration at the apex.[3]
Békésy concluded from these observations that by exciting different locations on the basilar membrane different sound wave frequencies excite different
In an article published posthumously in 1974, Békésy reviewed progress in the field, remarking "In time, I came to the conclusion that the dehydrated cats and the application of Fourier analysis to hearing problems became more and more a handicap for research in hearing,"[8] referring to the difficulties in getting animal preparations to behave as when alive, and the misleading common interpretations of Fourier analysis in hearing research.
Awards
Békésy's honours include:
